Asking, existing screwdriver the most not only has stubborn screw function, the most just has the most a protection against electric shock novel screwdriver, this screwdriver
Knife bar is divided into two sections, is connected by joint and groove between two sections of knife bars, be provided with insulating barrier between joint and groove, thus rise
To protection against electric shock effect.Get an electric shock although this screwdriver is prevented from people in use, but when cutter head relies on magnetic force sorption screw
When head is horizontally inserted in screw hole, screw afterbody is easy to glance off under self gravitation effect, the most also can fall
Fall.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of easy to use, it is possible to avoid screw in action of gravity

Entirety, front knife bar afterbody is provided with joint, and rear knife rod head is provided with the groove inserted for joint, is provided with between joint and groove
Insulating barrier, rear knife bar afterbody is connected with handle of a knife, wherein, front knife bar is cased with sleeve, and sleeve sets by front knife bar afterbody perisporium
The first thread segment put is threadeded with front knife bar, and when sleeve is snapped down on cutter head along front knife bar, sleeve can be enclosed within cutter head
Outside.
A kind of protection against electric shock novel screwdriver described in the utility model, wherein handle of a knife afterbody connects a T-shaped handle.
A kind of protection against electric shock novel screwdriver described in the utility model, the most T-shaped handle is provided with some anti-slip veins.
A kind of protection against electric shock novel screwdriver described in the utility model, wherein arranges the second screw thread on handle of a knife afterbody perisporium
Section, T-shaped handle is threadeded with handle of a knife by the second thread segment.
After using above structure, compared with prior art, this utility model one protection against electric shock novel screwdriver has following
Advantage: after cutter head relies on magnetic force to hold screw head, slides to sleeve knife bar afterbody in the past on cutter head, and is enclosed within outside cutter head
Portion, under the position-limiting action of sleeve, the skewness magnitude level of screw can be the least, does not falls out, and therefore, this utility model can be very
In easily screw being horizontally inserted screw hole and tightened.Additionally, when this utility model does not twists screw, can be by sleeve
It is screwed on the first thread segment of front knife bar afterbody, prevents loss.
The setting of T-shaped handle is easy to people and is gripped, and the most firmly, significantly improves the problem that screwdriver plastic handle skids,
